Immunocytochemical analysis of normal and acid maltase-deficient muscle cultures. 1985

A F Miranda, and S Shanske, and A P Hays, and S DiMauro

Muscle cultures from patients with infantile and later-onset acid maltase deficiency (AMD) and from unaffected controls were studied immunocytochemically with anti-acid maltase (anti-AM) antibodies and fluorescein-labeled goat anti-rabbit IgG second antibody. In control muscle cells, an intense granular distribution of staining was seen, consistent with lysosomal localization of AM. Cultured muscle cells from two patients with infantile AMD (Pompe's disease) did not fluoresce, whereas cells from two patients with AMD of later onset did fluoresce, showing a distribution similar to that of controls.

D005087	Glucan 1,4-alpha-Glucosidase	An enzyme that catalyzes the hydrolysis of terminal 1,4-linked alpha-D-glucose residues successively from non-reducing ends of polysaccharide chains with the release of beta-glucose. It is also able to hydrolyze 1,6-alpha-glucosidic bonds when the next bond in sequence is 1,4.	1,4-alpha-Glucosidase, Exo,Amyloglucosidase,Exo-1,4-alpha-Glucosidase,Glucoamylase,gamma-Amylase,Glucoamylase G1,Glucoamylase G2,1,4-alpha-Glucosidase, Glucan,Exo 1,4 alpha Glucosidase,Glucan 1,4 alpha Glucosidase,gamma Amylase
D005455	Fluorescent Antibody Technique	Test for tissue antigen using either a direct method, by conjugation of antibody with fluorescent dye (FLUORESCENT ANTIBODY TECHNIQUE, DIRECT) or an indirect method, by formation of antigen-antibody complex which is then labeled with fluorescein-conjugated anti-immunoglobulin antibody (FLUORESCENT ANTIBODY TECHNIQUE, INDIRECT). The tissue is then examined by fluorescence microscopy.

D006008	Glycogen Storage Disease	A group of inherited metabolic disorders involving the enzymes responsible for the synthesis and degradation of glycogen. In some patients, prominent liver involvement is presented. In others, more generalized storage of glycogen occurs, sometimes with prominent cardiac involvement.

D006009	Glycogen Storage Disease Type II	An autosomal recessively inherited glycogen storage disease caused by GLUCAN 1,4-ALPHA-GLUCOSIDASE deficiency. Large amounts of GLYCOGEN accumulate in the LYSOSOMES of skeletal muscle (MUSCLE, SKELETAL); HEART; LIVER; SPINAL CORD; and BRAIN. Three forms have been described: infantile, childhood, and adult. The infantile form is fatal in infancy and presents with hypotonia and a hypertrophic cardiomyopathy (CARDIOMYOPATHY, HYPERTROPHIC). The childhood form usually presents in the second year of life with proximal weakness and respiratory symptoms. The adult form consists of a slowly progressive proximal myopathy.
